STC (Sound Transmission Class)

STC Definition and Options
STC ratings are single number indicating the sound insulation value of a door or window (including partitions and floor-ceiling assemblies.) A door’s ability to reduce noise is called its sound transmission loss (TL) effectiveness.

TL is a value given in decibels (dB) which is determined by measuring sound pressure levels at a certain frequency in the source and receiving rooms.

See image using STC 39 as a sample -->

These values are fitted to a curve in a method defined by the ASTM E413 Classification Standard for Rating Sound Insulation. The higher the STC value, the better the rating and the better the performance.

Haley offers architectural doors with the following STC ratings, sub components, and gasketing:

Any unsealed gaps and clearances in door assemblies effectively cancel out the noise reduction benefits of STC rated doors. For example, 1⁄8″ clearances around the edges reduce the effective rating of an STC-52 door to STC-21!

Gasketing’s importance derives from a fundamental property of sound: Sound waves travel through any opening with very little loss. While the amount of air flowing through a gap increases in proportion with the size of the gap (see Figure 1) the size of the gap in a sound barrier does not matter (see Figure 2.) A tiny hole transmits almost as much sound as a much larger gap.
